Birr Castle Demesne combines astronomy heritage with a public garden and science-centre visit, including the restored Great Leviathan telescope and Ireland's Historic Science Centre. General admission covers the demesne rather than the private family home's interior; castle tours have separate seasonal arrangements. Wheelchair-friendly routes reach much of the site, and a lift serves the Science Centre, while some areas have restricted access.
